Before applying ac power to the 3468A,
check the rear panel line voltage option
label to be certain the instrument is set for the nominal line voltage in your area. If
necessary,
refer to the installation information in Chapter V. As you press the line
switch, carefully watch the display as the 3468A
goes through a complete inter-
nal self test.
DISPLAY
RESULT
The 3468A
performs a complete
inter-
nal
self
test
at
power-on.
Carefully
watch
the display,
especially
the
12
annunciators
along
the bottom.
Every
segment
in the display (except for the
top dot in the colon) is turned on for
approximately
2
seconds.
Following
this,
a complete
turn-on
self test
is
performed.
The
3468A
is then
reset
and
returns
to
its turn-on
state.
A
more complete description of the Self
Test is found in Chapter Il, page 25.
Should any of the five elements of the
self
test
fail,
a
message
will
be
displayed identifying the general circuit
area where
the failure occurred.
This
can
greatly
reduce
initial
trouble-
shooting time.
This entire
process
takes
only a mo-
ment
to complete.
At this
point
the
3468A
is ready to use and is set to
the following state:
Function:
DC Volts
Range: Autorange
on
Display:
5 1/2 Digits of Resolution
Trigger:
Internal Trigger
Auto-zero:
On
